Superb! A most fantastic micro-budget sci-fi movie. It may be hard to find a cinema playing it, but find one, now!
Six seemingly unrelated people wake up trapped in a three dimensional grid of cubes. Some of the cubes are safe, others are trapped. Unlike so many movies of this genre the intense tension is built skillfully on many dimensions.
The plight of the victims is captured well and the dialog only serves to increase the tension to unprecedented levels. The movie leaves your mind wandering for days. Not only about the predicament, but also who is behind the whole thing.
Try to visit their award-winning website, its superb. But here's a disclaimer: the movie is much better when seen with as little foreknowledge as possible. The site is well designed and gives away nothing. Click on the image to jump to their website.
